APW7095/A
6-Channel DC/DC Converter Control IC
Features
General Description
• Supports for synchronous rectification
(CH1, CH2 and CH5)
www.DataSheet4U•.com Supports for down or up-down Zeta conversions
(CH1 and APW7095 CH2)
• Supports for up, flyback or up-down SEPIC
conversions (APW7095A CH2, CH3, APW7095
CH4, CH5 and CH6)
• Supports for Inverting conversion
(APW7095A CH4)
• Low Start-up Voltage : 1.4V (CH6)
• Power Supply Voltage Range
- CH1 to CH5 : 3.0V to 6.5V
- CH6 : 2.4V to 6.5V
• 1% Reference Voltage Accuracy
• Wide Operating Frequency 100kHz to 1MHz
• Soft-Start Function (CH1 to 6)
• Power Good (PGOOD) Indicator for CH1
• Low Shutdown Current
• Output Short-Circuit Detections
• Lead Free Available (RoHS Compliant)
The APW7095/A is a 6-channel, frequency-settable,
voltage-mode, DC/DC control IC providing a complete
power supply solution for high-performance portable
digital cameras. The APW7095/A uses pulse-width-
modulation (PWM) and synchronous rectification for
high efficiency step-up, step-down, up-down and in-
verting converters with free input and output settings
in 2 or 4-cell AA, 1-cell lithium-ion (Li+), and dual-
battery designs. The APW7095/A incorporates error
amplifiers, output short-circuit detection, under-volt-
age lockout, soft-start and output switch control into
a chip. The AP7095/A improves performance, compo-
nent count, and size compared to conventional multi-
channel controllers.
The APW7095/A hasa power-good indicator (PGOOD)
that signals when CH1 output is within ±10% of the
set voltage by monitoring IN1 pin.
The APW7095/A is available in compact 48-pin plas-
tic LQFP and TQFN packages.
Applications
• Digital Camera
• Camcorder
• Hand-held Instrument
